watching ocean waves at the dock of the bay, Otis notices that 10 waves pass
beneath him in 30 seconds. He also notices that the crests of successive waves
exactly coincide with the posts of the dock that are 5 meters apart. What are
the period, frequency, wavelength, and speed of the ocean waves?

light has a longer wavelength than violet light. Which has the greater
frequency?
19.
If
a wave vibrates up and down twice each second and travels a distance of 20.0 m
each second, what is its frequency? Its wave speed?
20.
The
lowest frequency we can hear is 20.0 Hz. Calculate the wavelength (in feet)
associated with this frequency for sound that travels at 340.0 m/s.
21.
When
a wave source moves toward a receiver, does the receiver encounter an increase
in wave frequency, wave speed, or both?
22.
Does
the Doppler effect occur for only some types of waves or all types of waves?
23.
Astronomers
find that light coming from point A at the edge of the sun has a slightly
higher frequency than light from point B at the opposite edge. What do these
measurements tell us about the sun's motion?
24.
Would
it be correct to say that the Doppler effect is the apparent change in the
speed of a wave due to motion of the source?
25.
Distinguish
between constructive interference and
destructive interference.
26.
Is
interference a property of only some types of waves or of all types of waves?
27.
How
can you observe interference in sound waves?
28.
What
is a sonic boom? How fast must an aircraft fly in order to produce a sonic
boom?
29.
Whenever
you watch a highflying aircraft overhead, it seems that its sound comes from
behind the craft rather than from where you see it. Why is this?
30.

In
the following chart the columns indicate the light which is made available. The
rows indicate the color of paper when viewed in the available color. The reason
the paper has a color is that it reflects that color of light and absorbs all
others. Notice that the first column is when white (all colors) light is
available. Complete the remaining columns using your knowledge of the
colors of light and pigment. You are not required to use color algebra,
however, it works so try it.
